GAS BURNER AND GRA'IE.

To all whom it may concern."

Be it known that I, WILLIAM G. M0- GEORGE, citizen of the United States,residing at Oakland, in the'county of Alameda and State of California,have invented new and useful Improvements in Gas Burners and Grates, ofwhich the following is a specification.

This invention relates to improvements in gas grates and burnerstherefor.

One object of this invention is to provide a gas burner in which the gasis provided with nearly or quite all of the oxygen it requires forcombustion within the burner, thereby producing a flame of intense heat.

A particular object is to provide a gas log, or rather a gas grate, inconjunction with my burner, which is simple in construction and quicklyand easily installed, and economical of operation, which gives forth amaximum of heat and does not draw the oxygen from the room forcombustion, but rather delivers fresh heated air to the room.

The invention consists of the parts and the construction and combinationof parts hereinafter more fully described and claimed, reference beinghad to the accompanying drawings, in which Figure 1 is an end elevationand section showing the invention as applied. Fig. 2 is a front view ofthe burner with parts broken away.

In the drawings, A represents a log, preferably such as is made of firecla coated wit-h asbestos fiber on the outer sur ace, and of any desiredform of pile or artistic configuration, The construction of this log andits manner of heating and feeding air are important consideratlons. Thelog is hollow and is rovided with a number of orifices 2, suitab lydisposed above the burner 3 so that fresh air taken into the log fromany suitable source of supply will, after being heated, be deliveredinto the room above the flame, and without being used for purposes ofcombustion.

A common complaint against gas logs enerally, is that they consume theoxygen 1n the air in the room, and so impoverish the air that it isunfit to breathe, frequently causing headache and inconvenience to theoccupants. By using a special type of burner 3, which I shall shortlydescribe, whereby perfect combustion of the gas takes place "at theburneryand by supplying a Specification of Letters Patent.

constant flow of fresh air into and through the log, and discharging itout through the openings 2, I heat the room by hot air received from theoutside, rather than b the direct or reflected heat of the burner 'ame.In other words, this log constitutes, in fact, a hot air furnace.

The air to be heated in the log is drawn into the log through pipe lfrom any suitable point outside the room. This pipe may extend in thebasement or it may extend outside the building. As the log becomesheated up, a strong draft will be induced through the pipe 4: and log,and a series of streams of hot air will be thrown out into the roomthrough the discharge outlets 2. The burner 3 is arranged in front ofand beneath and parallel with the log and in close proximity thereto.This burner com prises a tube provided with a large number of smallperforations 6, and connects at one end by an elbow 7 to a mixing tube8, the opposite end of the burner tube being closed by a cap 9.

The mixing tube 8 connects with an enlarged air-tube 10, the outer endof which is open to the atmosphere. The connection between the air tubeand the mixing tube consists of a T-fitting 11, the stem of which may bethreaded upon a fixed standard 12, which supports the burner and holdsit in position.

A nipple 13, having a suitable gas tip 14 on its outer end, extendsthrough the T and projects a short distance into the mixing tube 8, andis connected with a flexible tube or hose 15 leading to any suitablesource of gas supply.

In operation, gas being admitted to the mixing tube 8 through the nipple13 and tip 14, it mingles with the air therein, which enters through theopen end of the pipe 10. This combustible mixture flows then through theconnection 7 into the burner tube 5 and On being ignited, t e flames ofthe burning gases dpass upward in a number of jets aroun the face of theasbestos-coated log A,-as shown in Fig. 1.-

The air tube 10 and its inlet are so proportioned in size in relation tothe mixing tube 8 and the flow of gas through the tip 14, as to permitof the proper mixture,

to be about seven parts air to one part gas.

The object is to secure perfect combustion at the burner so that none ofthe air issuing from the holes "2 in the log is used for comtube 10 toregulate the admission'of air to the burner necessary for complete'combu'sof, said member having perforations for tion.

In 'front of the burner there is arranged a hedge or wall 16, which actsbothto .cut 011' the view of the burner from the room and, to deflectthe heat and flame against the log.

;Having thus described my invention, what I claim and desire to secureby Letters Patent, is:

1. The combination with a hollow member into which fresh air isadmitted, said member having perforations for the .discharge of the air,a burner comprising a If desired, a damper valve may be placed over themouth of the airsaid hollow member.

The combination of a hollow meniber, a fresh air pipe leading to theinterior therethe discharge of the air,-and a burner positionedproximate to the hollow member and exterior thereto and adapted todischarge across the path of the heated fresh air being delivered fromsaid hollow member.

In testimony whereof I have hereunto set :my hand in the presence of twosubscribing witnesses.
